Feb. 25, 1958 G. J. vERHAs WINDOW WASHING AND CLEANING DEVICE Filed NOV. 5, 1954 A'rrnRNEYs Thisffinvention relates to window cleaning devices'oftheftypehavingfa pad-on the end off'fan elongated telescopinghandletq facilitate reaching fthe outside of glass panels of-a window 'sash or in which atpairfof pads are provided yonuthe ends of elongated arms of a lU-shaped handlewhereby inner and outer surfaces of glass panels ofwindow sash are cleaned'simultaneously and wherein the-necessity of -reachingoutside of thewwindovv'isob-v viatedt The purpose of this invention isk to eliminate the lardous task of cleaningouter surfaces of glass panelsofwindow sash, particularly 'of the double hung type.

Various types of holders and other devices lhaveebeen providedtfor washing and cleaning outerl surfaces of glass' panels @of the however, .it is difficult' to rreach overlapping ,sectionsf of the glass of'double-hung windows without sitting upon'thev window sill with the upper portion offthe-bodyronathey outside or without operating the cleaning devices through comparatively narrow 'openings with arms of thefoperator extended throughfthe openings Withthis thought in mind, this invention contemplates an elongated telescoping orfU-shaped` bracket Nhavingwindow cleaning. .pads pivotally mounted' at "one *end'eand' a handle positioned orifolneifside whereby 'the'device mayy be conveniently .held asiitA is'fope'r'at'ed for cleaning' inner and outer surfaces "of glass panels 'f of Window sash" with" the4 surfaces ofV the panels cleaned simultaneously.'

The Aobject'ofthis invention' is, therefore, to'provide means for freely mounting windowf cleaning pads onA the` ends of arms of a U-shapedbracket whereby `:outer surfaces ofglass panels of window sashmmay be readily cleaned from the inside of the window.

Another object of the invention is to provide a device for cleaning outer surfaces of glass panels of window sash in which the cleaning elements are readily removable and replaceable.

A further object of the invention is to provide a window cleaner having pads pivotally mounted at the end of an elongated handle in which the device is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies an elongated bracket formed with a pair of arms connected with an arcuate section providing a U-shaped structure with with window cleaning pads pivotally mounted on extended ends of the arms.

Other features and advantages of the invention will appear from the following description, taken in connection with the drawings, wherein:

Y The;` sheathis f also-:provided withffa @handle 23? which is fsecured, such as by weldingrztabsi--stamped on 'or bent; from" theendsgto thedface thereof; as shown-'in Figures; 1 and 6.

The :spring holding member :23' is A.provided with "slots 32and 33,`v thaty are' positioned to receive' the-bearings 15- and 16 whereby with the member 23 pressed downwardly with the pin 26 removed and with the tabs 19 and 20 positioned in the openings 21 and 22, the central portion of the spring member is pressed to a position below the tabs 19 and 20 whereby the tabs are adapted to be bent outwardly, as shown in Figure 2, for retaining the spring member in gripping relation with edges of the sheet of material 24.

The spring member 23 is formed with webs 34 and 35 having notches 36 and 37, respectively, therein and, as illustrated in Figure 3, the notches are positioned to receive points 38 at one side and 39 at the other of the plate 10 whereby the spring member with the points 38 and 39 provides positive gripping means for retaining the sheet of material 24 on the body of the pad. The web 34 is connected to the central portion of the member 23 with arms 40 and 41 and the web 35 is connected to the opposite side with arms 42 and 43. The points 38 are struck from openings 44 on one side of the plate 10 and the points 39 are struck from similar openings 45 at the opposite side.

With the parts formed in this manner, a sheet of window cleaning material, such as indicated by the numeral 24, is secured against the face of the pad, or plate 10, with the edges secured by the arcuate webs 34 and 35 of the spring member 23 and with the pad pivotally mounted Patented Feb. 25, 1958 by the pin 26 in the end of the arm 25 the pad is adapted to be worked over inner and outer surfaces of glass panels of window sash for cleaning the panels.

In the design illustrated in Figure 8, 'a` pair of pads 46, such as pads formed on the bodyorvplate 10, are pivotally mounted with pins 47 on the endsof arms 48 and 49 of a ilexible elongated member 60 which is slidably mounted in sections 50 and 51 of a U-shaped bracket 52 and the bracket is provided with a U-shaped handle 53, similar to the handle 28. The member 60 is coinpleted by having the lower ends of the arms 50 and 51 connected by an arcuate section 54 and the edges of the member 60 are rolled as indicated by the rolls 29 of the arm 25 and sheath 27. p

By this means one of the pads 46 is positioned on the inside of a window sash and thelopposite pad on the outside and with the arcuate section 54 extended through a comparatively thin slot at the lower end of the window the pads are adapted to be worked over inner and outer surfaces of glass panels of window sash whereby the sashes are readily cleaned without extending the arms or other `parts of the body of the operator through the window.

With the cleaning pads mounted in this manner a pad may readily be inserted between the sash of a double hung window and also between the outer surface of the sash and a screen positioned on the window. It is, therefore, not necessary to take screens down when washing or cleaning windows. l

The single arm cleaner, as illustrated particularly in Figure 1, is adapted to clean both the inside and outside surfaces of the glass, and with the cleaning pad held in this manner it may readily be actuated over the glass so that all parts thereof may be readily cleaned.

The cleaning sheet or material, as indicated by the numeral 24, may be chemically treated and may be removed and replaced, as desired.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention. t Y
